"Fighting Heart Disease With Pigs? San Diego Researchers Develop New Cardiac Therapy"
Randall Newman and his wife went on an 8-mile bike ride just days before he started feeling strange. "My arms started tingling, that?s when I was like this isn?t right," Newman said. Newman had a heart attack five years ago when he was 62. He said the heart attack was a surprise because he was normally feeling healthy. He wanted to try everything he thought could help him get better, including new therapies. "You know, try it," Newman said. "Everything can help to get your heart back to where it was," One of the things he was willing to try was pig hearts.

"What really weakens lithium battery efficiency?"
Powering devices as small as smartphones to those as large as electric vehicles, the rechargeable battery is a familiar technology to consumers. Work in the field of battery research continues, however, as researchers struggle to improve the efficiency and longevity of rechargeable batteries. State-of-the art Li-ion batteries offer fast charging but suffer from low power density. Research has therefore focused on optimization of battery anodes, cathodes, electrolytes, and even on replacement of lithium itself with other metals like sodium.

The firm, a University of California, San Diego spinout, began offering its small-input liquid volume extracellular RNA sequencing (SILVER-seq) service last week. "It measures extracellular RNA from a droplet of blood" or saliva, according to Sheng Zhong, a professor of bioengineering at UCSD and Genemo's founder.
"Thieves have been stealing credit card info at gas pumps. Now there's an app to foil them."
Last year, law enforcement officials found more than a thousand gas pumps nationwide that had been fitted with "skimmers" -- electronic devices that record credit card numbers and, in some cases, transmit them wirelessly over Bluetooth to a criminal's computer. This could have serious financial consequences for gas stations starting next year, when a law will require them to either spend thousands of dollars to install pumps that read the more-secure chips in credit cards or be liable for fraudulent charges. A new smartphone application could help law enforcement find skimmers

"Researchers Receive $3.1M to Study Heart Condition"
An international effort led by UC San Diego and Rady Children's Hospital researchers recently landed a $3.1 million grant to search for better ways of treating a pediatric heart condition. They're taking aim at Tetralogy of Fallot, a combination of four congenital heart defects. These defects cause oxygen-poor blood to flow out of the heart and to the rest of the body. Those with the condition typically undergo surgery before six months of age, and then another treatment once a toddler. But interventions can enlarge the right ventricle in the heart, increasing the likelihood of heart failure

"Crack-free ceramic welding at room temperature is a first"
A low-power pulsed laser has been used to weld ceramic materials together in room-temperature environments for the first time. The technique, demonstrated by Javier Garay at the University of California, San Diego and colleagues, could bring about diverse new applications for electronic and optoelectronic devices.
"Welding with Pulsed Lasers Protects Temperature-Sensitive Materials"
A new ceramic welding technology developed by engineers at the University of California, San Diego and the University of California, Riverside uses a series of short, ultrafast laser pulses to melt ceramic materials along the interface between two ceramic parts and fuse them together. Heat builds up only at the interface, so the melting is localized. The researchers call their method "ultrafast pulsed laser welding."
"California team tailors ultrafast laser pulse train to weld ceramics"
Engineers at the University of California San Diego believe they have made an important breakthrough for manufacturing ceramic materials, showing for the first time that certain types can be welded using pulses from an ultrafast fiber laser. While ceramics can be melted in high-temperature furnaces or using high-power continuous-wave lasers, conventional joining methods create so much heat that they cannot be used in close proximity to temperature-sensitive polymers or electronic components. That could now change.

"Researchers Get Closer to Design of 'Get Up and Go' Printed Robots"
One of the goals of robotics researchers is to achieve 3D printing of a soft robot with self-actuation that can be fabricated and then immediately walk away from the printer as a fully functioning machine. Researchers at the University of California San Diego believe they are a step closer to designing these so-called "get up and go robots" by embedding complex sensors into robotic limbs and grippers using a commercial 3D printer.

"Lasers Enable Welding of Ceramics"
Welded metal joints hold much of the industrial world together, and high-power lasers have revolutionized this type of welding over the past half century. Yet another important class of industrial materials--ceramics--stubbornly resist reliable welding using standard techniques. That difficulty has limited the use of ceramics in some important spheres, such as consumer electronics and medical devices, where these tough workhorse materials might be quite useful. Now, UC San Diego researchers may have resolved this conundrum--by putting ultrafast pulsed lasers and nonlinear optics on the case.

"Welding Ceramics With a Laser"
The process of making ceramics puts limitations on their use. Currently, ceramics are made by firing up a kiln and hardening them at temperatures up to a couple of thousand degrees Fahrenheit. Let's say that you want to encase a biomedical device in a ceramic capsule for implantation in a patient's body -- the temperature during the baking process would cook the electronics to a crisp. Now, researchers have developed a way to weld ceramics together using tightly focused, ultrafast laser pulses.

"Ultrafast lasers weld ceramics together at room temperature"
In theory, ceramics are great materials for encasing electronics. They're tough, they insulate against electricity, protect against heat, and in the case of implants in the body, they're biocompatible. The problem is that fusing ceramics together requires high heat, which would destroy electronic components. Now, researchers have developed a new way to weld ceramics together at room temperature, using ultrafast laser pulses.
